 `offs` is defined as CR32 (4x8) so as to mesh cleanly with Vectorised Rc=1 operations (see below).  Rc=1 operations start from CR8 (TBD).
 
-Notes from Jacob: CR6-7 allows Scalar ops to refer to these without having to do a transfer (v3.0B).  Another idea: the DepMatrices treat scalar CRs as one "thing" and treat the Vectors as a completely separate "thing".  also: do modulo arithmetic on allocation of CRs.
+The CR Predicates chosen must start on a boundary that Vectorised
+CR operations can access cleanly, in full.
+With EXTRA2 restricting starting points
+to multiples of 8 (CR0, CR8, CR16...) both Vectorised Rc=1 and CR Predicate
+Masks have to be adapted to fit on these boundaries as well.
